I disagree. You see typical celeb craziness almost always includes some kind of run-in with the police/rehab (Bieber, Lohan, etc.). As far as I know Miley hasn't had a DUI, hasn't gone to rehab, and hasn't been arrested. What we most likely have here is a very shrewd business strategy to manufacture controversy in order to drive album sales.

Tl;Dr: If she was really crazy she'd have had gotten in trouble with the one time.

You know if we're getting into 27 club territory, I wouldn't be too surprised if she started popping pills or drinking lean to keep up with this "gangsta druggie rep" thing she's going for, which could instigate an opioid addiction and an overdose.

But who knows for sure? It's not like what she's doing now is too far gone. Maybe she'll pull it together.
